OMAR F. NEFF, OF CHICAGO, ILLINOIS.

SMOKE-HOUSE.

Specification of Letters Patent.

Patented Dec. 23, 1915.

Application filed January 15, 1915. Serial No. 2,406.

To all whom it may concern Be it known that 1, OMAR F. NEFF, a citizenof the United States, and a resident of the city of Chicago, county ofCook, and State of Illinois, have invented certain new and usefulImprovements in Smoke-Houses, of which the following is a speciiication.

My invention relates to improvements in smoke-houses, and has for itsobject the production of a device of this character which will be ofimproved construction and efficient in operation.

Other objects will appear hereinafter.

rlhe invention consists in the combinations and arrangements of partshereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawings forming a part of this specification, and in which,

Figure 1 is a partially sectional front elevation of a smoke-houseembodying my invention, Fig. 2 is a vertical section of the device, Fig.3 is an enlarged section taken on substantially line :v -m of Fig. 1,and Fig. 4 is an enlarged top plan view of the smoke distributing memberprovided in the bottom of the smoking` chamber.

The preferred form of construction, as illustrated in the drawings,comprises a supporting frame consisting of four spaced upright angleirons 1. Arranged at the lower end of said supporting frame is acompartment 2 in which is slida'bly mounted a drawer 3 adapted, when thedevice is in use, to contain the burning coal, bark or other substancewhich is used in the operation of the device to produce smoke. r1`hefront side of drawer 3 adjacent the lower edge thereof is provided withdraft openings 4 which are controlled by a slidably mounted damper 5having corresponding openings adapted for registration with the openings4 and provided with an exteriorly projecting finger piece 6 foradjusting said damper. as clearly shown in Fig. 3. At its front side thedrawer 3 is provided with a handle 7 for facilitating opening andclosing of the same.

Leading from the upper side of compartment 2 and drawer 3 is anelongated pipe 8 of tortuous formation which is rigidly supportedbetween the angle irons l. The upper end of pipe 8 is in opencommunication with the bottom of a chamber 9 supported by the angleirons 1 at the upper ends thereof. Chamber 9 is accessible through adoor 10 provided at the front side thereof which is hinged at 11 andprovided at its free edge with a lock 12 whereby the same may be securedin closed position. Said door is also provided with a window 13 throughwhich the interior of chamber 9 may be viewed without the necessity ofopening the door.

Provided at the upper end of chamber 9 is a transversely extending angleiron 14 to the depending portion of which is secured a plurality ofhooks 15 adapted to support the pieces of meat, such as ham, bacon orthe like, which it is desired to smokel Leading from the upper end ofcompartment 9 is an outlet pipe 16.

The pipe 8, as will be seen, communicates with the bottom of chamber 9adjacent one side thereof, and in order to secure uniform distributionof the smoke introduced to said chamber throughout the interior of thelatter, a plate 17 is provided which is supported above the bottom ofchamber 9 upon an inwardly projecting supporting flange 18. The plate 17is provided with perfor-ations 19 which are of graduated size, beingsmallest adjacent the inlet opening into said chamber', saidperforations increasing in size as the same become more remote from saidinlet opening. Through this arrangement, it will be seen that the smoke,which is first introduced into the narrow space formed at the bottom ofchamber 9 between the plate 17 and the bottom of said chamber, will bedistributed throughout the interior of said chamber so that the articlesto be smoked, which are suspended above, will all receive uniformtreatment. lNithout the production of the plate 17 perforated, asmentioned, it is, of course, apparent that the pieces of meat, suspendedin close proximity with the inlet opening to the chamber 9, would besubjected to the treatment of a more dense smoke than the piecespositioned farther from said opening. In order to facilitate insertionor removal of the plate 17, the same is provided intermediate its endswith a hinge 2O which permits of folding of said plate during insertionor removal.

In the operation of the smoke-house. the smoke arising from the drawer 3will enter the lower end of pipe 8 and gradually rise in the latter,being introduced into the chamber 9 and distributed therein forengagement with the pieces of meat or other substance arranged in saidchamber in the manner Just described. Through the tortuous formation ofthe pipe 8, it will be seen, that rheat radiation than would be the casewith la pipe vof circular or square formation.

Also, by reason of the tortuous formation of said smoke pipe, aconstruction is produced which is compact and conlined. This cooling ofthe smoke before the same is introduced into the treatingl chamber is ofspecial advantage since it precludes the possibility of the cooking orbaking of the meat contained in said chamber during the smokingoperation, such as is universally the objection with smoke-houses ingeneral use at the present time. Through the construction set forth theabsolute cooling of the smoke before the same is introduced into thetreating chamber is insuredand therefore the objection mentionedobviated.

While I have illustrated and described the preferred form ofconstruction for carrying my invention into effect, this is capable ofvariation and modification without departing from the spirit of theinvention. I, therefore, do not wish to be limited to the precisedetails of construction set forth, but desire to avail myself ofv suchvariations and modilications as come within the scope of the appendedclaims.

Having described my invention what I claim as new and desire to secureby Letters Patent is:

1. A smoke-house comprising a smoke producing element; an elongatedsmoke passage leading from said element; a chamber in which the articlesto be treated are adapted to be arranged and into the bottom of whichsaid passage leads; and a foraminated foldable plate arranged in saidchamber adjacent the bottom thereof for uniformly distributing the smokeintroduced into said chamber throughout the latter, substantially asdescribed.

2. A smoke-house comprising a supporting frame; a smoke producingelement mounted in the lower end of said frame; a chamber in which thearticles to be treated are adapted to be arranged, mounted in the upperend of said frame; and a smoke pipo establishing communication betweenthe upper side of said smoke producing element and the under side ofsaid chamber, said pipe being of tortuous formation comprising aplurality of superposed convolutions interposed between said smokeproducing clement and said chamber, substantially as described.

3. A smoke-house*comprising a supporting frame; a smoke producingelement mounted in the lower end of said frame; a chamber in which thearticles to be treated are adapted to be arranged, mounted in the upperend of said frame; and a smoke pipe establishing communication betweenthe upper side of said smoke producing` element and the under side ofsaid chamber, said pipe being of broad liat formation in cross section,substantially as described.

fl. A smoke-house comprising a supporting element; a smoke producingelement mounted in the lower portion of said supporting element; achamber in which the articles to be treated are adapted to be arrangedsupported by said supporting element above and spaced considerably fromsaid smoke producing element; and an elongated tortuous smoke pipeestablishing communication between said smoke producing` element andsaid chamber, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
